im trying to do"type 1 then shows the calendar" program, but it keep jumping error!:"setcalendar(int) in calendar cannot be applied to()"!!!

anyone explain it to me and tell me how to correct it please! thanks!

You're refering to the setcalendar(int year) method without supplying a integer value. If this is not needed you could overload this method where there is no integer value needed.

thanks, but im still confusing, more help(especially the way how to solve it) please...

thanks, yes i know.
but how do i make the calendar an int???the calendar class is holding different variables , how can itself be an int???its so complex...

You're not trying to make a Calendar an int. The method you are trying to call expects you to send an int. The name of the parameter suggests that you should send an int indicating the year.

You don't need to make the calendar an int. In this code
you are calling the setcalendar() method. However, the setcalendar method is declared as
which means you need to pass an integer value which represents a year. So, as an example, to pass this year as an argument, you change your code to

problem sovled!!!thanks everyone!!!
